Hey all,
I searched around on this topic and I'm still a bit unclear so I'll throw out this question. I have a 2017 Tracker 195 with a Merc 150 four stroke. I am upgrading to a 24v trolling motor, and I'm installing two new graphs. I'm also upgrading my onboard charger to a three bank variety.
I want to install a battery selector switch that allows me to cut off all peripherals when the boat is not in use. When it's in the garage I'll keep the charger plugged in, but when the boat is away from the garage I need to minimize any draw on the batteries as much as possible. I also assume that the graphs will be drawing from the cranking battery, so I want the ability to switch to the trolling motor batteries to start my engine in the event the cranking battery is depleted while on the water.
I'm considering the Perko medium duty switch with Off/1/ALL/2 selector positions. I wondering if my assumptions are correct, and if so, how do I properly wire up the selector switch to accomplish my goal, and still permit me to charge all three batteries off the onboard charging system.
Thanks in advance for your help.
